Safety device for vehicle handles and vehicle handle comprising this safety device

Abstract

Safety device comprising an inertial mass ( 1 ) pivoted to a frame ( 2 ) for rotating around an axis ( 4 ), wherein elastic means ( 6 ) act on the inertial mass ( 1 ) for opposing its rotation, a wedge ( 12 ) being arranged in the frame ( 2 ) so that the inertial mass ( 1 ), when it rotates around this axis ( 4 ), slides along the inclined wall of the wedge ( 12 ), so as to axially move the inertial mass ( 1 ) along this axis ( 4 ).

The invention claimed is: 
     
       1. A vehicle handle of a motor vehicle, comprising:
 a frame; and 
 a safety device comprising:
 an inertial mass pivoted to the frame for rotating around an axis due to a force induced by an impact of the motor vehicle, wherein elastic means act on the inertial mass for opposing its rotation; and 
 a wedge arranged in the frame so that the inertial mass, when the inertial mass rotates around the axis, slides along an inclined wall of the wedge, so as to axially move the inertial mass along the axis in order to prevent the rotation of a rocker. 
 
 
     
     
       2. The vehicle handle according to  claim 1 , wherein the elastic means act on the inertial mass for opposing said axial moving. 
     
     
       3. The vehicle handle according to  claim 1 , wherein said elastic means comprise a helical spring arranged around said axis. 
     
     
       4. The vehicle handle according to  claim 3 , wherein the helical spring has an end in contact with a support of the frame and another end in contact with the inertial mass. 
     
     
       5. The vehicle handle according to  claim 1 , wherein the wedge is arranged beside the inertial mass. 
     
     
       6. The vehicle handle according to  claim 1 , wherein the inertial mass, when it has gone beyond the wedge during the rotation around said axis, is locked by the transversal wall of the wedge. 
     
     
       7. The vehicle handle according to  claim 1 , wherein the inertial mass and/or the wedge are provided with a tooth which can penetrate into a seat made in the wedge and/or in the inertial mass, respectively. 
     
     
       8. The vehicle handle according to  claim 7 , wherein said seat is made in the transversal wall of the wedge. 
     
     
       9. The vehicle handle according to  claim 1 , wherein the wedge is made in a single piece with the frame.
